In April 2012, O'Reilly hosted a webinar by the authors of the O'Reilly book "APIs: A Strategy Guide." Video and slides are below. The book is an overview of API strategy for business executives and this webinar dives into both public and private API strategies. Thanks to O'Reilly, @daniel_jacobson, @gbrail and @danwoodscito. Courtesy of O'Reilly, a free chapter is available here.
